Reader asks about a lack of power steering

Wheels:

Jeff asks: “The power steering did not work the other day when I started my 2015 Chevrolet Colorado pickup truck. However, if I shut off the engine and then restated it, it appeared to be working. This has happened several times. Any ideas?”

Halderman:

The Chevrolet Colorado pickup truck is equipped with an electric power steering (EPS) system and is not hydraulically operated as in many earlier pickup trucks. General Motors has issued a recall to correct the issue that can cause the loss of power steering assist. From the technical information, the cause appears to be related to a poor electrical connection within the steering gear connector that can cause a loss of power steering assist.
